valve cover gasket = head gasket? These two terms inconsistent on website. on 1997 Saturn SL1

is the "valve cover gasket replacement" the same as the "head gasket replacement" repair listed? If not, what is the pricing difference? Thank you.

Head gasket replacement is much more expensive than just the valve cover, however the valve cover needs to come off to get to the head.
